Product Brief

The rotary encoder is a device that can convert the rotation angle of the measured object into electrical signal, and is the core device of automatic measurement and motion control. MRE is a hybrid, large hollow, high precision capacitive rotary encoder. It is composed of the static disk and moving disk. The modulation circuit of the static disk transmits voltage pulses to the motor grid plate on the pattern surface of the static disk, and is coupled with the pattern plate on the moving disk; the static disk receives the signal with angle information, and the demodulation circuit amplifies, filters and calculates the signal, and calculates the angle value in real time.
